ABSTRACT
This is a short chapter: while the physics and chemistry of combustion can be extraordinarily complicated, and to this day aren't fully understood, we will boil it down to a very simplified model. Our two main sources in graphics are the papers by Nguyen et al. [NFJ02] for thin flames, and those by Melek and Keyser [MK02] and Feldman et al. [FOA03] for volumetric combustion. There are of course many other approaches that avoid fluid simulation and directly model flames procedurally, but we will not cover them in this book.
